我正在使用MYSQLi(来自此网站:http://codular.com/php-mysqli)并获取空白页。
<html>
<body>
<h1>TEST21</h1>
<?php
error_reporting(E_ALL); ini_set('display_errors', 1);
$db = new mysqli('localhost', 'Brendan', 'password', 'Library');
if($db->connect_errno > 0){
die('Unable to connect to database [' . $db->connect_error . ']');
}
echo "STEP1";
//STEP 2
$sql = <<<SQL
SELECT *
FROM 'BOOK'
WHERE 'ISBN10' > 0
SQL;
if(!$result = $db->query($sql)){
die('There was an error running the query [' . $db->error . ']');
}
echo "STEP2";
?>
</body>
答案 0 :(得分:4)
HEREDOC令人讨厌的事情是,结束标识符不能有任何前导空格(不得缩进)。请参阅此处的重大警告 - http://php.net/manual/language.types.string.php#language.types.string.syntax.heredoc
您还在查询中使用了错误的引号字符。我简化了这一切......
$sql = 'SELECT * FROM `BOOK` WHERE `ISBN10` > 0';
